Thank you for posting this work! So far I understand BTC is more traceable in the chain than cash in global circulation. What's to be done to improve security?

On a side note, if the heists are trackable, has anyone done any crunching to see how many bits of coin are lost or floating around? From lost wallets to abandoned fractional mining payments. Curious what this sum is worth and whether anything can be done - Also how this affects the inflation/deflation value of the coins.
